Bonus Skills and Ranks: The eldritch brawler selects three sorcerer skills to add to her class skills in addition to the normal brawler class skills, one of which must be Spellcraft. The eldritch brawler gains a number of ranks at each level equal to 4 + Int modifier.

Weapon and Armor Proficiency: The eldritch brawler is proficient with all simple weapons plus the handaxe, short sword, and weapons from the close fighterweapon group. She is also proficient with light armor. The eldritch brawler can cast sorcerer/wizard spells while wearing light armor without incurring the normal arcane spell failure chance. Like any other arcane spellcaster, an eldritch brawler wearing medium armor, heavy armor, or uses a shield incurs a chance of arcane spell failure if the spell in question has a somatic component. A multiclass eldritch brawler still incurs the normal arcane spell failure chance for arcane spells received from other classes.

Bloodline: At 1st level, an eldritch brawler gains the sorcerer’s bloodline. She may select any bloodline listed in the sorcerer’s bloodline description, and gains her bloodline powers at 1st, 3rd, 9th, 15th, and 20th level. At 4th level, she gains her bloodline arcana. An eldritch brawler gains no bloodline spells or bonus feats. This ability replaces martial flexibility, martial training, and the bonus feats gained at 2nd, 8th, 14th, and 20th level.

Spellcasting: Beginning at 4th level, an eldritch brawler gains the ability to cast a small number of arcane spells drawn from the sorcerer/wizard spell list. To learn or cast a spell, an eldritch brawler must have a Charisma score equal to at least 10 + the spell level. She can cast spells she knows without preparing them ahead of time. The saving throw DC against an eldritch brawler's spell is 10 + the spell level + the eldritch brawler's Charisma modifier.

Like other spellcasters, an eldritch brawler can cast only a certain number of spells of each level per day. Her base daily spell allotment is given on Table: Eldritch Brawler. In addition, she receives bonus spells per day if she has a high Charisma score. The eldritch brawler does not need to prepare these spells in advance; she can cast any spell he knows at any time, assuming she hasn't yet used up his allotment of spells per day for the spell's level.

The eldritch brawler's selection of spells is limited. At 4th level, an eldritch brawler knows two 1st-level spells of her choice. An eldritch brawler gains more spells as he increases in level, as indicated on Table: Eldritch Brawler Spells Known. Unlike spells per day, the number of spells an eldritch brawler knows is not affected by his Charisma score. This ability replaces maneuver training.

Brawler’s Strike (Su): This is exactly like the brawler ability of the same name, except that the eldritch brawler gains each increment of this ability as shown on Table: Eldritch Brawler.

Knockout (Ex): This is exactly like the brawler ability of the same name, except that the eldritch brawler gains this ability at 6th, 12th, and 18th level.
